EDGE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 374,314, dated December6, 1887.

Serial No. 236,769. (No model.)

To all whom it may concern:

Be it known that I, PATRICK llIOLAUGHLIN, a citizen of the UnitedStates, and a resident of Quincy, in the county of Norfolk and State ofMassachusetts, have invented new and useful Improvements in Edge-SettingMachines, of which the following, taken in connection with theaccompanying drawings, is a specification.

This invention relates to improvements in edge-setting machines forboots or shoes, and

. drawings.

a is a suitable frame, in bearings a a a of which is located the rotarydriving-shaft I), provided with fast and loose pulleys b b, as shown inFigs. 1 and 2. The shaft b has on it between the bearings a and a acrank or eccentric, b*, to which is pivoted the rear end of theconnecting-rod c, the forward end of which is pivoted to the block d,that is guided in longitudinal grooves made in the frame a and itscap-plates a e, as shown in the drawings, and by this arrangement areciprocatory motion is imparted to the block d from the rotarycrankshaft 11 b If so desired, a circular brush, e, may be secured toone end of the shaft 1) for the purpose of making a wax finish on theboot or shoe sole edges, as is usual in machines of this kind.

To the reciprocatory block at is secured at a right angle, or nearly so,the tool-carrier f, in perforations in which are vertically adjustablethe edge-setting tools 9 and h, such tools being secured in place on thetool-carrier f by means of set-screws g h or equivalent devices. Byhaving the tool-carrier f arranged as shownthat.is, projecting at aright angle to one side of the stationary frame a-the operator hasabundant space in which to freely handle and manipulate the work to bedone,

and as very little obstruction is made to his vision he can easily seeat all times the progress of the work.

The tool g is intended for the purpose of setting the sole-edge aroundthe toe and sides of the sole, and the tool 72. is adapted for use insetting the edge at the shank portions of the sole-edge.

In connection with the tool 9, I use a stationary guard, g, secured tothe frame a in a suitable manner, and said guard is provided with aVertical perforation, 9, through which the lower end of the tool gprojects and in which it can move freely forward and back. This guard ghas a convex under surface, as

shown in Figs. 2, 3, and 5, and it serves to protect the shoe-upper oredge of the sole from injury in case the shoe-sole is accidentally runoff from the tool during the operation of setting the edge of the toeand side portions of the sole-edge. The guard does not serve as a restfor the sole, and the latter is not intended to come in contact with orto bear against said guard, except when the sole is accidentally run offfrom the tool, when it serves as a guard to prevent injury tothe'sole-edge or shoe-upper.

In connection with the tools 9 and h, I use an adjustable heating devicethat is carried out as follows: To the side of the frame a, I secure bymeans of a set-screw, i, or similar device, the arm or bar I, the latterhaving in its lower end a slot, z", through which passes the aforesaidset-screw t, as shown in Figs. 1, 2, and 3, and by this arrangement thebar or arm I may be adjusted up or down, or swung forward or backrelative to the frame or, according to the desired position of theflames or burners. To the upper end of the arm I is pivoted thehorizontal pipe K, which may be freely turned around its axis in itsbearing in the upper end of the arm I. If gas is to be used as a heatingmedium, I provide the pipe K with a flexiblepipe, k, leading from anysuitable gas-supply in the building. To the pipe K are secured the pipesZ and m, having gas burners or wicks l m in their forward ends, arrangedat right angles to the respective pipes Z m, as shown in Figs. 1 and 2,so as to cause the flames from said wicks or burners to heat the upperends of the tools 9 and h. Where it is not conven ient to use gas, I usethe pipe K as an oil-res- ICO ervoir and lead wicks from it through thepipes Z and m to effect the proper heating of the tools 9 and h. By thearrangement of the adjustable arm I, the pipe K, turning therein, andthe heater-pipes Z m, secured to pipe K, it will be seen that I caneasily adjust the positions of the burners or wicks Z m relative to thetools 9 h, as may be desired, before, during, and after the performanceof setting the sole-edges, and this can be done without causing theflames from the wicks or burners to come in contact wit-h or injure thework. As may be desired, the burners or wicks Z m may be so adjusted bythe means above described as to cause the flames to heat the upper orlower parts of the tools g h, according to the heat required on thelatter, and may as easily be swung out of reach of the said toolswhenever so desired.

This machine is very simple and compact in construction. It can be runat a great speed with a minimum ofpower. The progress ofthe work caneasily be ascertained at all times. All accidental injury to thesole-edge or upper is prevented by the use of the perforated stationaryguard, and the heating device for heating the reciprocatory tools ismade so adj ustable as to be under the instant control of theoperator,and so arranged as to prevent the flames from coming in contact with orinjuring the work.

What I wish to secure by Letters Patent, and claim, is

1. The improved edge-setting machine, as

described, consisting of the frame a, the rotary crank-shaft b If,located in bearin gs therein, the connecting-rod 0, connected to crank band the reciprocatory block d having secured to its forward end thetool-carrier f, projecting to one side of the frame a, and havingadjustably secured to it the edge-setter tools g h, as and for thepurpose set forth.

2. The stationary frame a and the block d, adapted to bereciprocatedtherein,and thetoolcarrie'rf, secured to the block d and having adjustably secured to it the edge-setter tool 9, in combination with thestationary guard 9, having perforation through which the lower portionof the tool 9 projects, as and for the purpose set forth.

3. In an edge-setting machine, the herein described adjustable heatingdevice, consisting of the arm I, having slot 2" and set-screw z, bymeans of which it is adjusted and secured to the frame a, said armhaving pivoted to its upper end the horizontal pipe K, provided withpipes Z m, having the side wicks or burners Z'm, combined with thereciprocatory edgesetter tools 9 h, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence oftwo subscribing witnesses, on this 26th day of November, A.D. 1886.
